background: fetal alcohol syndrome is associated with numerous problems in the development and function of the brain. learning and memory deficits are among well known effects of prenatal exposure to alcohol. objective: this study aimed to examine the spatial working memory of 60-day old rats who were exposed to alcohol during their fetal life and to find the relation between the possible alcoh...
The design of microwave filters and multiplexers usually starts with the synthesis of an equivalent circuit for determining the optimal architecture of the device. One can observe that the requirements for filtering devices in the last-generation of communication systems have broadened the area of traditional filter synthesis. In the recent years, many studies have concerned the synthesis of ad...
Up to now, production systems only concern was to minimize production costs or optimize the utilization of production resources. But with the increasing energy prices and the growing concern over the environmental impact of production systems (industrial systems consume a quarter of all energy), efficient use of energy in manufacturing environment cannot be ignored any longer. MANUbuilding conc...
Introduction There are two questions with all programs and efforts to industry development in Iran: I) How much is rate of environmental hazard of industries in each Iran regions? II) How much is rate of capital production of industrial sector to environmental damages in regions of Iran? Explanation and Interpretation of the Results In recent years (2009-13), despite a reduction i...
This study was conducted in metalwork and woodwork industries in Jeddah Industrial Estate. The purpose of this study was to assess the magnitude of industrial noise exposure and to propose remedial actions. Noise was measured at different times of a day in 28 randomly selected factories and workshops. Results indicated that noise levels varied according to the type and size of a factory, and th...
In this article, we describe a practical drug discovery project for third-year undergraduates. No previous knowledge of medicinal chemistry is assumed. Initial lecture workshops cover the basic principles; then students, in teams, seek to improve the profile of a weakly potent, insoluble phosphatidylinositide 3-kinase delta (PI3Kδ) inhibitor (1) through compound array design, molecular modellin...

Reconfigurability/tunability has become an essential feature of modern agile RF and future mm-wave apparatuses and systems for wireless communications, sensing and imaging. In the coming decades there will be a paradigm shift towards smart, cognitive and agile wireless sensing (including imaging) and communication systems. The use of mm-wave frequencies will lead to communications systems showi...
